Listen to Joe Rogans podcast with sleep scientist Mathew Walker, it's very informative, one thing he talks about are sleep aids and how they are actually worse for you, you never get in full REM sleep, you are putting your self to sleep artificially. Your body needs to be able to sleep naturally, no weed, cbd, melatonin, Ambien. Rogan was blown away seeing he uses marijuana for sleep for over 20 years.
